Ocean Defender

Dive into an action-packed underwater defense adventure in Ocean Defender. A beautiful coral fortress is under attack, and you are its last line of defense.

Command a powerful ocean cannon and stop waves of hostile sharks before they reach the reef. Aim carefully, fire expanding nets, collect coins from defeated enemies, and strengthen your cannon across seven upgrade levels. When the fortress shield becomes damaged, use your earnings to restore it and keep the reef protected.

Fight through five increasingly challenging waves filled with standard and armored sharks. Survive the final assault and defeat the enormous Abyss Titan to secure the ocean.

Ocean Defender features colorful underwater graphics, responsive controls, three difficulty modes, multilingual support, strategic upgrades, and extended wave-based gameplay for desktop and mobile browsers.
